THETFORD — Officials in a small Vermont town say more than half the town’s road signs have been stolen over the past few months.

Thetford Public Works Director Scott Knowlton said 50 of the town’s aluminum signs identifying the names of roads have been pilfered, possibly for to sell as scrap metal, but none of the town’s traffic signs have been stolen.

The Valley News reported that the town on Thursday ordered 27 replacement signs from the state’s prison system, where inmates produce them, and expects to order more in the coming weeks.

Police Chief Jim Lanctot said the thefts could potentially cause problems for emergency response vehicles responding to calls and for out-of-towners who aren’t familiar with the town.
